By nice wheels, I don't just mean olympic speed skating on straightways, and people who are familiar with hockey seldom do.
Krug, yes, his straightaway speed over distance is average at best, but acceleration and lateral movements are fairly elite, which is often allows him the ideal angles for moving in from the point and putting pucks on net. Faulk is similar, his speed is slightly above average, but his skating is not only strong, but agility is superior; all you have to see is the all star competitions that he participated in. Perunovich is definitely quick, and also has above average speed, definitely not going to lose a foot race against most skaters in the NHL, he's not going to blow anyone away, but he doesn't need to with his agility.
Faster, yes we do indeed get faster, a bit on straight line speed, but much more in terms of the D-corps ability to do quick break outs, and accelerate through the neutral zone after broken plays. I'm not sure what you mean by "nip it in the bud", but the narrative you are pushing is inaccurate at best.
